The NBA games on Network TV average 4.7 million viewers. 3.4 million in its first broadcast is a barometer of the interest thats out there for boxing. Most of these NBC cards are not going to out-do NBA basketball or pro football games. They simply are not.
What would you normally expect for a fight on a Friday night and on Spike? You wouldn't expect that great of a card in the first place that's some really good reference to go off of.
